From the moment I created my very first critter in my Woodland Critter series, I have wanted to create other groups under the Critter umbrella. So, finally I have begun the Aquatic Critters. Right now, that consists of the Colossal Whale, the Nimble Octopus, The Playful Porpoise and the Patient Seahorse.
More subsets, sub-series, etc. to come.
These are available in my Etsy shop.
